'To all whom it may concern:

.Be it known that I, Prune Deuces, a sub- Cook and-State of Illinois,- have; invented certain new and useful Improvements in Brooms for Street-Sweeping Machines; and

reference being had to the accompanying drawings, and to the numerals of reference marked thereon,:which form a part of this Fig.3 is a transverse vertical section of the-broom.

heretofore constructed-,haveshad 1 the broom straws or ratan glued in which is not. only a te'diousoperationbut an' ex'pensive one as Well. Also much. difiiculty has been experienced in replacing worn out straws or ratan.- Y

It is an object of this invention to. provide a street sweeping machine broom; in." which the broom drum-017' inandrel-fis constructed of interfitting-apertured' sections, each of whiehis provided with means "to engage in the apertures to firmly bind .the-

straws or ratan' in place.

It is a further object of this inventionto provide adevice} of the class specified in -which repairs may be quickly made. by. the

removal of one ormore sections to permit the ready removal of old or worn-fibers and the insertion of the proper number of new- I It isfurther' an object of this invention to provide a device of the class, speclfied'. inwhich'transverse 'passages or apertures arestraw, ratan or broom fibers after which the sections mav again be clamped together to firmly bind the fibers in place. I

provided in the sections thereof-for the insertion of theproper number of broom fibers and inwhich said sections are 'pro videdwi'thinterfitting ribs and teeth adapted to engage in or partlvfill the apertures toform a mechanical and positive binding element for firmly attaching the broom fibers in place.

The invention (in'a preferred form) is illustrated in the drawings and hereinafter more fully described.

communicate with the apertures 5, and are openthrough the inner side of the section.- This section '2, is also cored outto provide] a rectangular recess 14, also shown in dot The section (Fig;- 6) isprovided with oppositely disposed ribs 15-16,, having; teeth 17'1'8,- respectively integral there section isprovided with .rows of fiber-rewith. As show-n in dotted lines a'cored out recess 19, "is provided in one side of section row of apertures 9, forlasuitable dis or approximately half-the r diameter, Between the apertures 9, the walls of the-sec '3, andov'erlaps therow'of passages 7, and a cored-out recess 20, is prov ded in the-opposite side of said section and overlaps the ance tion are cored out. to provide passages 21,

which communicate with thepassages 8, and open outwardly through one. slde of-the sec-' tion.

As shown in Fig. fl, the section'gisprovided with a rib 22, having teeth 23, integral therewith. Section 4 is also pro- .vided' with arectangular recess 24, which overlaps the row, of apertures 10, to about half their diameter. A plurality of passages 25, are provided in the wall of section 4, between the apertures 10, which passages connect with the apertures 11, outwardly and open through one side of the section.

All'of the ribsand teeth on the difl'erent sections are offset so as to fit above and below each other .to permit the respective side of the sections to abut one another when the broom is assembled. l

'The operation is as follows:

-A suitable number of fiber bundles 26, are

inserted in the apertures -5, 6, 7, 8,9, 10 and 11, after whichthe sections are clamped together. When sections 2 and 3 are placed together theteeth 17, project through the passages 13, into the row of apertures 5. As

shown in Fig. 4, rib engages in the recess 14, of section 2, and rib 12 of section 2, en-

apertures 6 the teeth 18, engage in the passages 25, and

project into the respective rows .of apertures 8 and 11. .Also rib 16, engages in recess 24, in section 4, and rib 22, engages in the rectangular recess 20, in section? v The respective ribs 22 and 16, project into the respective rowsof apertures 9 and 10.

When thesesections 2, 3, and 4, are clamped together with the tufts of broom fiber in place the respective teeth and ribs interfitting in the recesses and passages firmly bind and wedge the fiber tufts or bundles in position.

The main sections are clamped together b means of bolts 27', which extend through afined apertures 28, in the end and middle auxiliary sections;

As shown in the present case three auxiliary sections comprise one main quarter of the drum or one drum section and the duter sections 2 and 4, are beveled as at 29, Fig. .4, to properly interfit with the other main drum sections. However, it is obvious that as many auxiliary sections as desired may form one main drum section.

The main drum sections are secured to end plates 30, which are connected on a shaft 31, in any suitable manner.

Mlany details of construction may be varied and numerous changes may be made in the arrangement of the sections and bindelements without departing from the rlnciples of this invention and I therefore so notdesire to limit the patent when issued otherwise than necessitated bythe prior art.

. I claim as my invention:
